POSTER MOISTENING MACHINE Original Filed June 25, 1927 INVENTOR. VV/LL/HM Rex BELL By s rfia f fihi ATTORfl Patented Apr. 26, 1932 UNITED STATES PATENT. OFFICE f1 WILLIAM REX BELL, or manna Hanan; InLIAnA POSTER MOISTENING EMAGHINE Original application filed June 25, 1927, Serial No. 201,369. Divided and this application filed March 1928. Serial This invention relates to a device for moistening poster material for borders, partitions and the like but which in larger sizes can be employed for moistening sheets to be 5 handled in roll form.

The chief object of the invention is to moisten poster material and remove from the same any excess moisture and arranged the same in moistened condition and in an 19 arrangement that can readily be handled and which will permit of the removal of the moistened paper with a minimum of difficulty.

The chief feature of the invention in addition to the process herein disclosed, consists in. the provision of means for accomplishing the same, which means is such that it will supply to the poster material a substantially uniform amount of water and when thus tempered will remain in tempered condition for a reasonable length of time for subsequent use.

The full nature of the invention will be understood from the accompanying drawings and the following description and claim In the drawings Fig. 1 is a top plan view of a moistening device embodying the invention. Fig. 2 is a side elevation of the same.

This application is a division of the copending application, Serial No. 201,369, filed June 25, 1927.

In the drawings 10 indicates a framework having suitable compartments 11 for the reception of moistened paper, posting copy or border material, the same being wrapped in oil cloth or similar material to retain the moisture imparted to the moistened rolls so that the rolled material will remain in tempered condition for the desired length of time. A perforated top 12 is supported by the frame 10 and is adapted to receive folded sheets in unfolded relation, if and when desired, and said sheets may then be immersed in a tank 32 and rolled upon a shaft 33 mounted in the open bearings 34.

The present invention, however, is shown including additional mechanism for moistening rolls of posting paper and the power and control therefor includes an electric motor 23 controlled by a foot pedal 24 connected by a link 25 to control mechanism 26. Mounted upon the shaft 33 is a pair of adjustable end plates 35 guiding a roll 36 of blanking or border paper for posting. The roll revolves in the tank 32 which is supplied with water. Paper 37 passes upwardly over a friction and severing strip 38 which is relatively smooth and serves to scrape the surplus moisture from the sheet 37 and such excess drips upon the drip plate 39 and is returned to the tank. The sheet 37 is rolled up upon shaft 40 mounted in an open bearing 41 at one end and having a universal connection 42 at the opposite end. The sheet is anchored to the shaft by an elongated spring clip in the form of a partial cylinder 27 and indicated by dotted lines in Fig. 2. The shaft 40 is rotated by the stub shaft 43 to which it is connected by said universal joint 42 and said stub shaft is rotated by the pulley 44. driven by belt 45, in turn driven by the pulley 22. A recording device having the indicating arm 51 movable adjacent a scale 52 is associated with the roll upon shaft 40 so that the amount of blanking paper can be accurately determined in a roll and thus only sufficient paper necessary for the borderof each sign or display will be moistened when mounted in any one roll.

The present device secures tempering of poster material with just sufficient amount of moisture requisite therefor, evenly distributed and at relatively great speed and with a low labor cost. The moistened poster material then is in such shape that it can be mounted upon the posting panels or boards without creasing or wrinkling and without applying glue or paste to the exposed face of the posting material, such as heretofore has been required.

If desired, the shaft 40 may be removed from the roll or may be included therein and a sufficient amount of paper is usually included in said roll so that there will be sufiicient rigidity in the roll so as to be self-sustaining in spite of the moistened condition of the paper. The roll may be handled as if the same included therein a supporting shaft.

The invention claimed is:

A poster copy moistening machine in- 100 eluding a tank adapted to contain a moistening liquid for conditioning and tempering poster copy, a support in the tank for a supply roll, the roll being adapted for full emersion in the tank and for rotating therein, a second roll support Without the tank and adapted to receive copy unrolled from the supply roll and rolled thereon to obtain sub, stantially uniform tension therein, power means for rotating said second roll support, a scraping plate for removing from the intermediate strip between the rolls and returning to the tank excess surface liquid carried therefrom and arranged to cooperate for severance of the strip, and measuring means associated with the rewind roll for indicating the accumulated footage for strip severance into rolls of't'he desired length.

In Witness whereof, I have hereunto aflixed my signature.
